GOLDQUEST REPORTS 43 METRES GRADING 7.88 G/T GOLD AND 1.41% COPPER FROM PRE-FEASIBILITY DRILLING AT ROMERO PROJECT
Goldquest Mining Corp. has released the results of the first three drill holes of its recently completed six-hole 2015 drill program on its 100-per-cent-owned Romero gold/copper deposit in the Dominican Republic. The holes were designed to move inferred material to the measured and indicated categories that will allow it to be included in feasibility-level economic studies. All holes met or exceeded expectations in terms of grade and thickness, based on the existing mineral resource block model.
Highlights include LTP-169, which intersected 43 metres of 7.9 grams per tonne gold (cut) and 1.4 per cent copper, equalling some of the highest grades drilled at Romero, which included eight metres grading 29.3 g/t gold (cut) and 2.2 per cent copper, and the best interval being two m grading 119.7 g/t gold (uncut) and 5.24 per cent copper. This interval exceeded expected grades and thickness based on the mineral resource block model. This intercept is estimated to be true width based on the known geometry of the zone. In addition, hole LTP-168 reported two separate intercepts of 85 metres grading 2.39 g/t gold and 0.41 per cent copper, and 48 metres grading 1.17 g/t gold and 0.46 per cent copper.
"These first three holes tested areas of inferred resources, away from the high-grade core of the Romero deposit. Hole LTP-169 exceeded our expectations based on the block model grades and highlights the potential to increase the amount of high-grade material outside the core deposit area," commented Julio Espaillat, president and chief executive officer. "As we move the Romero project forward it is anticipated that minimal further drilling, if any, will be needed for the prefeasibility study."

All the results and subintervals summarized in the table have a top cut-off of 72 g/t of gold as supported in the Oct. 29, 2013, National Instrument 43-101 mineral resource estimate. Interval widths may not represent true thickness of the deposit. All holes are inclined. LTP-168 was drilled at an azimuth of 40 degrees with a dip of minus-55 degrees, LTP-169 was drilled at azimuth of 180 degrees with a dip of minus-55 degrees and LTP-170 was drilled at an azimuth of 225 degrees with a dip of minus-85 degrees.
The hole locations are shown on the map at the company's website.
The Romero prefeasibility drill program was designed to improve the confidence in the mineral resource estimate, collect geotechnical and hydrology data for the mine design, and to supply material for the next phase of metallurgical testwork. All holes have been completed with assays remaining from three holes. All of the holes have been logged for geotechnical data to refine the underground mine design, and the geotechnical study by SRK Engineering is in progress. Immediately following the assaying of the half-core samples, the remaining material was put in cold storage to prevent oxidation, and thus provide reliable and readily available material for metallurgical testing planned for the prefeasibility study.
Holes LTP-168 and LTP-169 are criss-crossing angled holes which targeted an area of inferred mineral resources outside of the core of the Romero deposit which were included in the preliminary economic assessment and are scheduled to be mined in the early years of the mine. Hole LTP-169 intersected higher-than-expected gold and copper grades, and cuts through the deposit perpendicularly, and thus the mineral interval represents the true width of the deposit in that area. Hole LTP-168 was drilled at an angle to the north to gather geotechnical data close to the planned main ramp for the Romero mine and to improve confidence in the deposit. Hole LTP-170 is a steeply dipping hole which targeted inferred resources approximately 300 metres to the southeast of the core of Romero.
The company will release the results of the remaining three holes when its analysis is completed.
As part of the company's quality assurance and quality control procedures, most of the high-grade intervals are reassayed and the company is awaiting these check samples. In addition, systematic reassaying of intervals is in progress, to confirm compliance of blanks and duplicates checks. The company also reviews results from certified standard reference materials (CRSM), which are inserted at a rate of five per 100 samples. Within the results disclosed herein there were two samples that had results above the recommended tolerances, one for gold and the other for copper. A portion of the batches will be reassayed. In Goldquest's drill programs, composite intervals were chosen using a combination of geological criteria and mineralization, averaging around two m core length. The drill core is cut in half with one-half of the core sample shipped to Acme Labs by Goldquest technicians. The remaining half of the core is kept at the company core shack for future assay verification or any other further investigation. Assays within intervals below the 0.005 g/t detection limit for Au were given a zero value. All drill samples were prepared and screened by Acme Labs (Vancouver); metallic fire assay and multielement ICP-MS were assayed by Acme Analytical Laboratories (Vancouver). Gold values are determined by standard fire assay with an AA finish, or, if over 10.0 g/t Au, were reassayed and completed with a gravimetric finish. QA/QC included the insertion and continual monitoring of numerous standards, blanks and duplicates into the sample stream, at random intervals within each batch. The comprehensive Goldquest quality assurance and quality control protocols can be viewed on Goldquest's website.
